Definitions

• the invention relates to a fume hood of a cooker hood, which is designed to accommodate at least one fan housing and at least one fan housing enclosed motor and impeller, in particular a radial fan, with a suction opening for receiving the vapor from a cooking area. Furthermore, the invention relates to an extractor hood.
• Extractor hood enclosing ventilation devices, in particular axial or radial fan with corresponding fan housings through which a flow is set in the extractor housing, which serves for the extraction of vapors and vapors, which may arise during cooking, for example.
• the axial or radial fans are accommodated in fan housings, for example in the form of worm housings.
• a fan housing has for this purpose usually one or two suction port (s) and an outlet opening, which is provided at vertically formed radial fans on the top of the fan housing.
• the extractor hood is provided on hoods. Through this extractor housing a guide channel for the air to be discharged can be created to the intake of the fan housing. Furthermore, the extractor hood of the extractor hood separates the concentrated polluted airflow from the ambient air, i. from the kitchen air, and picks up the fan housing to form an engagement protection.
• extractor hood extractor hoods include a cover member which may have an outlet opening for the fan housing and two side walls, a rear wall and a front cover.
• various electronic components such as a power supply, a control board or a capacitor, may be necessary.
• the wiring of the electronic components together takes place in the known extractor housings usually by a connector strip.
• the various electronic components are enclosed by a so-called electronics box, which includes these components, as well a person, for example a fitter, protects.
• This electronics box is often arranged in the vapor extraction housing known from the prior art on the outside of the extractor housing. That is, it is known to arrange the electronic components or the electronics box either on the side of the extractor housing or on the extractor housing. Furthermore, it is known to provide on the side walls of the extractor housing a recess or depression in which the electronic components or the electronics box are arranged. Finally, it is known to arrange the electronic components or the electronics box on the top of the fan housing.
• extractor housings in which a recess or depression is provided in the side walls of the extractor housing in order to receive the electronic components or the electronics box there is the disadvantage that through this recess or recess, the inside of the extractor housing is not smooth, which adversely affects the flow path of the sucked vapors and the sucked-in vapor. Through the recess or depression can cause turbulence of the flow, which significantly worsens the exhaust performance of the fan.
• the arrangement of the electronic components or the electronics box on the top of the fan housing has the disadvantage that the electronic components after installation of the fan housing in the fume hood housing are barely accessible or no major effort. For this purpose, first the extractor hood, that is, the panel of the extractor hood would have to be removed. Repairs to such arranged electronic components thus represent an enormous amount of time. The increased assembly costs are costly.
